Application filed January 18, 1916. Serial No. 72,815,

To all whom it may concern:

Be it known that I. JosrPI-r A. ZIMMER- MAN, a citizen of the UnitedStates, residing at South Bend, in the county of Pacific and State ofVashington, have invented new and useful Improvements in Saw-Sets, ofwhich the following is a specification.

This invention is an improved saw set adapted for use for setting theteeth of saws appropriately for sawing wood or timber of various kindsand also adapted for setting the teeth of hand saws, the object of theinvention being to provide an improved device of this kind which isextremely simple in construction, is strong and durable, may be readilyoperated and by means of which the teeth of saws may be accurately setfor any purpose desired.

The invention consists in the construction, combination and arrangementof devices, hereinafter described and claimed, reference being had tothe accompanying drawings, in which Figure 1 is a perspective view of asaw set constructed and arranged in accordance with my invention. Fig. 2is a detail front elevation of the same on a larger scale than that ofFig. 1. Fig. 3 is a detail plan on the same scale as that of Fig. 2.

In accordance with my invention I provide a setting plate or anvil 1which is here shown as contracting in width from its inner to its outerend and is also shown as provided on its under side with supportingteeth 2 to support the same on any supporting surface such as a bench,log, or the like.

At the front end of the plate or anvil is a series of set notches, eachof which presents an inclined surface 3. These set notches are ofvarious depths and have their setting surfaces arranged at variousinclinations according to the angle at which saw teeth are to be set toenable the saws to be used for sawing timber of various kinds'inclination and is of proper depth for setting the saw teeth for maple,the notch 6 is for beach, the notch 7 for hemlock, the notch 8 for pine,the notch 9, for fir or spruce, the notch 10 for cork or bass wood, thenotch 11 for teeth of a hand saw, and the notch 12 for oak. I alsoprovide an arm 13 which is made of spring steel and the rear end ofwhich is reversely bent and flattened to form a U-shaped spring 1 1, thelower arm of which is secured in a recess on the center and at the rearend of the anvil plate 1 by means of screws 15. The spring 1 1 adaptsthe front or free end of the arm 13 for vertical movement. as at 16 toprovide a spring portion which adapts the arm 13 to be moved laterallyabove the anvil plate. A setting element 17 is secured on the front endof the arm 13 and has a pointed lower end 18 and is provided with abroadened upper end or head 19 adapted to be struck by a hammer.

In the operation of the device, the saw is placed on the anvil platewith one of its teeth over an appropriate setting recess, accordingtothe kind of wood, for which the saw is to be used, and by placing thepoint of the setting element 17 on the saw tooth and striking the headof said setting element by means of a hammer, the saw tooth willbe setat exactly the required angle as will be understood. The spring portions14, 16, of

the arm 13, enables the setting element to be arranged over any desiredset recess and used in connection therewith, for setting the teeth forvarious sizes. The said setting element may be slightly adjustedlongitudinally of the arm 13, to compensate for the angular movement ofsaid arm and is here shown as screwed by means of a suitable set screw21.

Having described the invention, what is claimed is: V

1., A saw set comprising an anvil plate provided at one side with aseries of setting notches, an arm mounted on said plate and arranged forvertical and also for lateral movement and a setting element at the freeSaid arm 13 is narrowed, vertically end of the arm adapted to bearranged in operative relation to any one of the series of settingnotches.

2. A saw set comprising an anvil plate provided at one side with aseries of setting notches, an arm mounted on said plate and arranged forvertical and also for lateral movement and a setting element at the freeend. of the arm adapted to be arranged in In testimony whereof I aflixmy signature operative relation to any one of the series in presence oftWo Witnesses.
